Z., assignor of thirty-fiveone-hundredths to Clemens A. Keck Application March 25, 1946, SerialNac'sassi This invention relates to an anchor insert adapted forembedding in concrete ceilings, or floors, or walls or any concrete baseand designed for having articles or any member attached or anchoredthereto. 3

In its broadest aspects, the invention consists of a metalshell whichmay be of any suitable sh'apeor de ign, but which preferably tapers fromone'iend to the other to produce a wedging reaction. when embedded in'concrete and which shell carries some anchoring means to whichattachinents may be made. In addition, the shell may be providedfwithstabilizing means for maintaining the same in proper position when-theconcr'ete'is' poured and with anchoring provisions in its walls forforming a bonded relation with the concrete after it has been poured andset.

The invention comprises the novel structure and combination of partshereinafter described and more particularly pointed out and defined inthe appended claims.

In the accompanying drawing which illustrates a preferred form of thisinvention and in which similar reference numerals refer to similarfeatures in the different views:

Fig. 1 is a perspective view of an anchor insert involving thisinvention;

Fig. 2 is a top plan view of the same;

4 Claims. (Cl. .72-105 Fig. 3 is a fragmentary perspective viewillustrating certain modified features;

Fig. 4 is a part sectional and part elevational view of an applicationof this invention to a concrete floor; and

Fig. 5 is a view similar to Fig. 4 illustrating a modification of thisinvention and an application' thereof.

In referring now to the drawing, there is shown an exemplification ofthis invention comprising a meta1 anchor insert having side walls 6 andwalls I. The width of each side wall tapers toward its lower end forminga truncated pyramid. The side walls are punched out at spaced points toprovide openings 8 with outwardly directed flanges 9 at the upper andlower ends. The fluid concrete will pass through these openings betweenthe flanges and form a bond that further serves to anchor the inserts inthe concrete. The lower end of the insert may be provided with aperturedtabs [0 which may be fastened to a concrete form and also lateraltongues II which serve as supports. The tabs l0 preferably extend fromthe sides of the insert anchor and the tongues H extend from the ends.

At the bottom of the insert, there is an open work chamber 12 which isformed by a partition 2 I plate-l 3 having end tongues l4 extendingthrough slots inthe end walls and positioned a suitable distance abovethe bottom of the insert. This plate is provided with a slot l5 bestseen in Fig. 2 through which a bent anchor wire [6 extends and which isprovided with a coil or eye I! at its intermediate portion below thepartition plate. From this coil, the two branches of the wire divergeupwardly withthe end portions l6a bent at angles and extending throughopposite slots l8 in the end walls and a distance therebeyond, wherethey are adapted to .be embedded in the concrete.

If desirable, the lower. edge ofthe anchor in: sert may be provided withtangs l9 as s'howngiri Fig. 3 for piercing wood forms or the woodde'ck20 in buildings or the like as shown in Fig. 4 for stabilizing theanchor insert. This may be especially desirable when concrete forms arenot convenient for attachment to the lugs l0.

An application of the invention is shown in Fig. 4 in connection with aconcrete floor 2| of a building with the wood decking 20 at the bottomthereof. In this application of the invention, the tangs [9 are used andthey are shown driven into the wood decking. The insert anchor is shownembedded in the concrete withthe wire coil or eye I1 in the work chamber[2 which is substantially free of concrete. A suspension member 22 whichshould be of suitable design for supporting whatever article desired canbe fastened to the eye I! for supporting any object. In Fig. 4, thesuspension member is shown in the form of a wire hook hitched to the eyeand with an anchor hook 22a at its lower end carrying a bar or beam 23to which the furring bars 24 for a ceiling are attached. Metal lath forplaster are adapted to fasten to the furring bars 24. Of course, it willbe understood that a large number of anchor inserts may be necessary andused for accomplishing the desired purpose. In the present instance,only one has been shown.

While the anchor insert has been illustrated as supporting a ceiling, itwill be understood that it may support pipes, lamps or any otherarticle.

In Fig. 5, there is shown a modified form of the invention in which themetal anchor eliminates the wire anchor l6 and a block of wood 25 issubstituted therefor. The top of the insert here is flush with the topof the concrete floor or wall and serves as a nailing medium for floorbeams 26 or the like or as a nailing medium for any other purpose.

When a concrete floor or wall is made, such anchor inserts will belocated at the desired points and secured in proper stabilized positionsbefore the concrete is poured around them so that they will becomeproperly embedded therein.

From the foregoing, it will be apparent that a novel anchor insert hasbeen provided that is adapted for all general purposes; that can readilybe embedded in concrete ceilings, walls, concrete bases or the like toprovide suitable anchors for diff erent obj act-S.

I am aware that many changes may be made and various details ofconstruction may be modified without departing from the principles ofthis invention, so I do not propose limiting the patent grantedotherwise than necessitated by the appended claims.

I claim as my invention:

1. An anchor insert for embedding in concrete comprising an open endedmetal shell having slots in opposed walls adjacent the upper endthereof, and a transverse partition plate spaced from the, ends, and ananchor member compris ing a wire having an, eye located below said paretition and diverging arms extending from said eye-thru said partition,said arms terminating in; a gular por i ns. extending thru said slotsfor embedding. in concrete beyond said shell.

2., anchor insert for embedding in concrete comprising a, truncatedtapering shell having slots in opposite walls at the end of greatestdimension, a partition spaced from the other end, and. an. anchor memberwithinsaid shell having means at one end extending thru said slots forembedding in concrete beyond said shell and having means at the otherend extending thru and be ond said partition for anchoring an o jtherein 3. An anchor insert for embedding in concrete comprising a metalshell having a partition plate spaced inwardly from one end, an anchormember within said shell having laterally extending parts extending thruopposite walls of said shell adjacent the end remote from said partitionplate, said ancho member extending thru said partition plate and havingfastening means in the space beyond said partition plate.

4. An anchor insert adapted for embedding in concrete comprising a metalshell open at both ends and having a partition spaced inwardly from oneend, and an anchor member within said shell having anchoring meansextending beyond the wall of said Shell and anchor fastening meansextending thru said partition adapted for attachment to an, QbJ' ecttobe anchored.
